SPEUIFICATION forming part of Letters Patent No. 544,662, dated. August 20, 1895.

Application filed March v22, 1895. Serial No. 542,812. (No model.)

To all whom, it may concern.-

Be it .known that I, THOMAS JEFFERSON OLEPPER, a citizen of the United States, residing at Columbia, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Ash-Sifter, of which the followingis a specification.

This invention relates to au improvement in ash-sitters, and has reference particularly to that class of ash sitters in which a rotary cylindrical sieve is employed, having a removable section or door for permitting the introd uctiou and removal of the coals and cinders and mounted in a two-part case or box having a hinged top for adapting said cylinder to be removed, and with a removable tray or pan for catching the dust, coal, dac.

The object of the invention is to provide a simple, compact, and durable construction of ash-sitter having a rotary cylindrical sieve or screen and in providing said cylindrical screen with a removable section or door of novel construction, to simplify and improve the construction of saiddoor and the means by which the same is held in position; also, to provide said cylindrical sieve or screen with means whereby it may be held against rotation in such position as to enable the operator to remove and replace the door thereof.

To this end the invention consists in certain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings,'and pointed out in the claim.

In the accompanying drawings,.-Figure 1 is a perspective view of an ash-sitter constructed in accordance with my improvements. Fig. 2 is a side elevation ot' the same withthe adjacent side of the case or boxY partly broken away to show the interior arrangement. Fig. 3 is plan View of the same. Figt is a detail perspectiveview of the removable section or door of the cylindrical sieve or screen.

Similar numerals of reference indicate corresponding parts in the severaligures of the drawings.

Referring to the drawings, the inclosing case or box is made in two parts or sections, a lower rectangular section l and a correspending rectangular upper part or section 2 hinged thereto at the rear. The case or box as a whole is supported upon feet or legs 3,

preferably made of iron and formed in two oppositely-dsposed pairs, which are hinged to the bottom of the box and adapted to be folded inward for storage, transportation, &c. Suitable pivoted braces 4, secured to the under side of the box and adapted to bear at their ends against said feet or legs, hold the latter rmly in position when in operative position, as shown. y

5 designates a rotary cylindrical sieve or screen, comprisinga pair of hanged end disks 6, mounted upon a horizontal shaft or axle 7, mounted in suitable bearings 8 at either end in the top side edges of the lowerpart l of the case or box, said bearings being left open at the top or made U-shaped to permit the removal Aof the screen or sieve when desired. A screen of woven wire or perforate sheet metale'xtends nearly around the end disks 6, extending -transversely-from one to the other, a sufficient gap or space being left between .the ends of the screen to form an opening for the introduction and removal of the ashes. A removable section or door 9, adapted to cover said gap or space, consists of astout rectangular metal frame 10 covered with wire netting or perforate sheet metal, as shown, and provided at either end with corresponding perforations 11, and also provided 'in either end bar with notches or open slots 12, the purpose of which will appear. The removable section or door 9 is curved or concave-convex in cross-section, adapting it to lit snugly over the opening in the cylindrical screen. An oppositely-disposed pair of radially-projecting pins 13 on the cylindrical sieve end disks, are adapted to engage the perforations 11 in the rectangular frame of the door 9, their purpose being to guide and direct said door to its proper position and to relieve the springholding catches from strain.

The spring-catches indicated at 14 are secured to the opposite outer faces of the end disks 6 and extend at their outer ends through notches 15in the outwardly-projecting anges 16 of said end disks, and also through the notches or open slots 12 in the removable section or door 9, where they are provided with inwardly-projecting catch-lips 17, for engag ing the door-frame, and with inclined faces 18, for facilitating the application of said door tothe cylinder. By means of the construction just described the removable section or door is firmly held in place and end or lateral movement thereof prevented.

Upon one end, outside of the case or box, the shaft 7 is provided with a disk 19, having one or more depressions or notches 20 for the reception of the free end of apawl 21, pivoted to the case. Outside thereof said shaft is provided with an operating-crank, by means of which the screen or sieve is located. The notches or depressions 2O are located at such a point in the disk that when the pawl 2l is in engagement therewith the door 9 of the cylindrical screen or sieve will be uppermost.

Beneath the cylindrical screen is located a tray or pan 23 for receiving the dust, coals,

`43:0., and removable through an opening in the front end of the box or :inclosing case, said opening being closed by a hinged door 2l, held in place by means of a catch or button 25. This door 24 and also the hinged top 2 of the inclosing-case are formed in such manner as to make a close and dust-tight joint with the part l of said case, so that when closed the dust cannot possibly escape therefrom.

In operation, after the ashes have been put in the cylindrical sieve or screen and the top or lid 9 fastened down, as above described, the hinged top of the inclosing-case is then closed and the cylinder then turnedk slowly until the dust is completely separated from the coals and cinders, after which the dust is allowed to settle. The pan or tray is then removed and the dust or refuse thrown out. The pan is then returned to its place, the door of the cylinder removed, and the coals and cinders dumped into the pan or tray and removed When wanted for use. By providing the disk 19, notched as described, and the pivoted pawl engaging said disk, it will be apparent that the removable section or door of the cylinder may be brought uppermost without the necessity of opening the case or box.

The ash-sitter above described is easy of operation, is absolutely dust-proofthere is nothing to get out of order, and will be found thoroughly efcient in practice. By reason of the simplicity of its construction it may be manufactured at slight cost and will elect a great saving in fuel.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

In an ash sifter, a rotary cylindrical screen or sieve, the oppositely disposed pins or guides at either end thereof, and a pair of spring catches also arranged at either end of the cylinder and secured thereto, in combination with a removable section or door, the oppositely disposed perforations therein for engaging said pins or guides, and the end notches for the reception of said spring catches, all arranged substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
